Install SafeNet eToken PRO on Ubuntu 16.04 LTS

Since I run Ubuntu on my workstation at work I need a working eToken, so every time I upgrade (follow LTS releases) I have to make sure the eToken works. Because some have reported the installation steps I have described for 14.04 are not working for 16.04 I have decided to update the steps for the latest LTS.

Dirk-Jan,
another question: do you happen to know how to make cisco anyconnect vpnui to read etoken (or speak to SACserv)?
It works only via Firefox secure device for me like described on Alladin howto page http://www.aladdin-rd.ru/support/faq/etoken/category3/faq1000448/ (sorry in Russian, but it’s the best short howto I managed to find), starting vpnui via java. If I use standalone vpnui it gives me:
“Please ensure that your eToken is inserted and contains a valid authentication certificate.”
so it never reads etoken.
I tried adding etoken into /opt/cisco/anyconnect/profile/vnpclient.xml but it did not work, perhaps missing something.
Any idea? or maybe you can point me to the right direction.
Thanks
